I'm using the latest Firefox 73.0 on Ubuntu 18.04.
And I'm using the DarkReader AddOn (Or here at GitHUB) at night, which takes care of automatically creating a dark background to reduce eyestrain. Except for some minor (well...) inconveniences, it works great on SO and other sites.
But one problem still remains: When I open a new page (or refresh it), there will still occur a blinding white background for a second or so (or even more) before the background turns black. This is highly annoying.
How can I get rid of that?
And is this a browser bug or one of DarkReader?
